About System4 of Delaware
System4 of Delaware provides commercial janitorial and facility cleaning services across New Castle County and northern Delaware, maintaining a 4.8-star rating from 24 client reviews. Operating from Newark, the company serves businesses in Wilmington, New Castle, Middletown, Bear, and the surrounding areas, offering round-the-clock cleaning support for offices, medical facilities, warehouses, and specialty commercial properties. Their service menu spans routine janitorial maintenance, electrostatic disinfection, and post-construction final cleans, addressing the diverse sanitation needs of Delaware's business community.
What distinguishes System4 of Delaware is their specialization in COVID-19 cleaning and disinfection protocols, a service line developed during the pandemic and now integrated into their facility management approach. The company offers electrostatic disinfection services using hospital-grade methodology, targeting healthcare facilities, daycare centers, and medical offices where pathogen control matters most. Their day porter services provide ongoing daytime support for high-traffic facilities, ensuring continuous maintenance rather than after-hours-only service.

Alex and Joe receive recognition for rapid response, with one reviewer describing a Friday walkthrough followed by full cleaning execution within a week.
